TECHNICAL FIELD

Embodiments of this application relate to the field of communicationstechnologies, and in particular, to a polar code encoding method andapparatus.

BACKGROUND

Channel coding, as a most fundamental wireless access technology, playsa vital role in ensuring reliable data transmission. In an existingwireless communications system, a turbo code, a low-density parity-check(LDPC) code, and a polar code are usually used to perform channelcoding. The turbo code cannot support information transmission at anexcessively low or high code rate. Due to encoding/decodingcharacteristics of the turbo code and the LDPC code, for medium andshort packet transmission, it is difficult for the turbo code and theLDPC code to achieve ideal performance in case of a limited code length.In terms of implementation, the turbo code and the LDPC code haverelatively high computation complexity in an encoding/decodingimplementation process. The polar code is a high-performance code thathas been theoretically proved to be capable of achieving a Shannoncapacity and that has relatively low encoding/decoding complexity, andtherefore is applied increasingly widely.

However, as the wireless communications system evolves rapidly, a futurecommunications system such as a fifth generation (5G) communicationssystem has some new characteristics. For example, three most typicalcommunications scenarios include enhanced mobile broadband (eMBB),massive machine type communications (mMTC), and ultra-reliable and lowlatency communications (URLLC). A higher requirement is imposed forencoding/decoding performance of a polar code in these communicationsscenarios.

Reliability sorting of polar channels play a vital role inencoding/decoding performance of a polar code. However, in the currentphase, accuracy of the reliability sorting of the polar channels is notideal, affecting further improvement of the encoding/decodingperformance of the polar code in an application process.

In a possible design, the sorted sequence may alternatively berepresented by using normalized reliability sequences or equivalentreliability sequences of various channels. For example, a sortinglocation of a channel x in the foregoing sequence is n (where a smallestsequence number in the sorted sequence is denoted as 1). In this case,reliability of the channel may be represented as n or normalized n/N.

In a possible design, locations of fewer elements in the sorted sequencemay be exchanged. For example, a sequence number location may beadjusted by a specified magnitude, for example, the specified magnitudeis 5. A location of an element whose sequence number is 10 may beadjusted by left and right five locations.

DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

The following describes in detail the embodiments of this applicationwith reference to accompanying drawings.

Embodiments of this application provide a polar code encoding method andapparatus. According to a principle of a polar code, a polarizationoperation affects reliability of each polar channel, so that some polarchannels have high reliability and some have low reliability. Selectinga polar channel having higher reliability to transmit information bitscan achieve good transmission performance. The embodiments of thisapplication are based on the basic principle of the polar code. Abitwise construction method for each mother code length is used, toobtain a sorted sequence for polar code construction. This can betterreflect actual channel reliability, helping improve accuracy ofreliability sorting of polar channels and improve encoding/decodingperformance of a polar code.

For convenience of understanding the embodiments of this application, apolar code is briefly described below.

According to an encoding policy of the polar code, a noiseless channelis used to transmit information useful to a user, while a pure noisychannel is used to transmit agreed information or is not used totransmit information. The polar code is also a linear block code. Anencoding matrix of the polar code is G_(N). An encoding process is x₁^(N)=u₁ ^(N)G_(N)·u₁ ^(N)=(u₁, u₂, . . . , u_(N)) is a binary rowvector, and has a length of N (namely, a code length). G_(N) is an N×Nmatrix, and G_(N)=F₂ ^(⊗(log) ² ^((N)))·F₂ ^(⊗(log) ² ^((N))) is definedas a Kronecker product of log₂ N matrices F₂. The foregoing matrix

$F_{2} = {\begin{bmatrix}1 & 0 \\1 & 1\end{bmatrix}.}$

In the encoding process of the polar code, some bits in u₁ ^(N) are usedto carry information and are referred to as an information bit set, anda set of indexes of these bits is denoted as A. The other bits are setto fixed values that are agreed on by a receive end and a transmit endin advance and are referred to as a fixed bit set or a frozen bit set(frozen bits), and a set of indexes of these bits is denoted as A^(C)that is a complementary set of A. The encoding process of the polar codeis equivalent to: x₁ ^(N)=u_(A)G_(N)(A)⊕u_(A) _(C) G_(N)(A^(C)). Herein,G_(N)(A) is a submatrix obtained based on rows corresponding to theindexes in the set A in G_(N), and G_(N)(AC) is a submatrix obtainedbased on rows corresponding to the indexes in the set A^(C) in G_(N).u_(A) is an information bit set in u₁ ^(N), and a quantity ofinformation bits is K. U_(A) _(C) is a fixed bit set in u₁ ^(N), aquantity of fixed bits is (N−K), and the fixed bits are known bits.These fixed bits are usually set to 0. However, the fixed bits may beset to any value provided that the value is agreed on by the receive endand the transmit end in advance. In this way, encoded output of thepolar code may be simplified as x₁ ^(N)=u_(A)G_(N)(A). Herein, u_(A) isthe information bit set in u₁ ^(N), and u_(A) is a row vector having alength of K. In other words, |A|=K, where |⋅| represents a quantity ofelements in a set, K is a size of an information block, G_(N)(A) is thesubmatrix obtained based on the rows corresponding to the indexes in theset A in the matrix G_(N), and G_(N)(A) is a K×N matrix.

A construction process of the polar code is a process of selecting theset A. This determines performance of the polar code. The constructionprocess of the polar code usually includes: determining, based on a codelength N of a mother code, that there are N polar channels in total thatrespectively correspond to N rows of the encoding matrix; computingreliability of the polar channels; and using indexes of first K polarchannels having higher reliability as elements in the set A, and usingindexes corresponding to the remaining (N−K) polar channels as elementsin the set A^(C) of the indexes of the fixed bits. A location of theinformation bit depends on the set A, and a location of the fixed bitdepends on the set A^(C).

The sorted sequence in the embodiments of this application is used torepresent reliability sorting of N polar channels, where N is a mothercode length of a polar code, and N is a positive integer power of 2.

Generally, the sorted sequence may include sequence numbers of the Npolar channels, and the sequence numbers of the N polar channels arearranged in the sorted sequence based on reliability of the N polarchannels, for example, may be arranged in descending order of thereliability or in ascending order of the reliability. For convenience ofdescription, the sorted sequence is referred to as a Q sequence.

In another case, the sorted sequence may include values of reliabilityof the N polar channels. Optionally, the values of the reliability maybe a value of normalized reliability or a value of equivalentreliability. For example, a sorting location of a channel x in thesorted sequence is n (where a smallest sequence number in the sortedsequence is denoted as 1). In this case, reliability of the channel maybe represented as n or normalized n/N. Similarly, the values of thereliability of the N polar channels may be arranged in the sortedsequence in descending order of the reliability or in ascending order ofthe reliability. For convenience of description, the sorted sequence isreferred to as a Z sequence. It can be known that the Q sequence and theZ sequence may be mutually converted. That is, if the Q sequence isknown, the Z sequence may be obtained, and vice versa.

Values of elements in the sorted sequence may be from 0 to N−1, or maybe from 1 to N. In the embodiments of this application, that the valuesof the elements in the sorted sequence are 1 to N is used as an examplefor description. It can be learned that 1 may be subtracted from a valueof each element in the sorted sequence to obtain a sorted sequence inwhich values of elements are 0 to N−1. The two sorted sequences havesame performance, and both of them can represent reliability sorting ofN polar channels. For the sorted sequence designed in the embodiments ofthis application, arrangement is performed in ascending order ofreliability is used as an example for description. It may be understoodthat all elements in the sorted sequence may be arranged in reverseorder to obtain a sorted sequence in which elements are arranged indescending order of the reliability. The two sorted sequences have sameperformance, and both of them can represent reliability sorting of Npolar channels.

As shown in FIG. 1, a communications system 100 to which an embodimentof this application is applied includes a transmit end 101 and a receiveend 102. The transmit end 101 may also be referred to as an encoder, andthe receive end 102 may also be referred to as a decoder. The transmitend 101 may be a base station, and the receive end 102 is a terminal.Alternatively, the transmit end 101 is a terminal, and the receive end102 is a base station. The base station is an apparatus deployed in aradio access network and configured to provide a wireless communicationfunction for the terminal. The base station may include macro basestations, micro base stations, relay stations, access points, and thelike in various forms, and may be applied to systems of different radioaccess technologies, for example, to more possible communicationssystems such as a long term evolution (LTE) system or a fifth generation(5G) communications system. The base station may further be anothernetwork device having a base station function, and particularly, mayfurther be a terminal that serves as the base station function in D2Dcommunication. The terminal may include various handheld devices,in-vehicle devices, wearable devices, or computing devices having awireless communications function, or another processing device connectedto a wireless modem, and various forms of user equipments (UE), mobilestations (MS), and the like.

Based on the architecture of the communications system shown in FIG. 1,in the embodiments of this application, the polar code encoding methodmay be performed by the transmit end 101. The following describes indetail the polar code encoding method provided in the embodiments ofthis application.

Based on the architecture of the communications system shown in FIG. 1,as shown in FIG. 2, a specific procedure of a polar code encoding methodprovided in an embodiment of this application is as follows:

Step 201. Determine a sorted sequence used to encode to-be-encoded bits.

The sorted sequence is used to represent reliability sorting of N polarchannels, N is a mother code length of a polar code, and N is a positiveinteger power of 2.

Step 202. Perform polar code encoding on the to-be-encoded bits by usingthe sorted sequence, to obtain encoded bits.

A length of the to-be-encoded bits is K, the K to-be-encoded bits aremapped to K of the N polar channels, and reliability of the K polarchannels is higher than reliability of remaining N−K polar channels.

In an actual application, the sorted sequence may be stored offline.After a transmission parameter (for example, a code length and a coderate) is given, the prestored sorted sequence is used to determine apolar construction method, to be specific, determine an information bitset and a frozen bit set that are used for polar code construction. Forexample, a polar code construction method may be obtained through tablereading.

The following specifically describes how the sorted sequence applied tothe embodiments of this application is obtained.

First, in a process of obtaining the sorted sequence in thisapplication, a sequence performance comparison rule may be applied. Theembodiments of this application provide an example of the performancedetermining rule, but are not limited thereto.

The sorted sequence needs to satisfy a simple nesting characteristic.That is, after a sorted sequence having a maximum mother code length isdetermined, another sorted sequence having a shorter mother code lengthmay be obtained based on the sorted sequence having the maximum mothercode length. A possible performance determining rule is as follows:

Evaluation metrics: signal-to-noise ratio (signal-to-noise ratio, SNR)required for a block error rate (block error rate, BLER) to reach 10⁻²and 10⁻³.

Simulation and Assumption:

Additive white gaussian noise (additive white Channel gaussian noise,AWGN) channel (channel) Modulation mode Quadrature phase shift keying(quadrature phase shift keying, QPSK) Information code K = [8, min(200,K_(max, N))], where K_(max, N) = block length K └5N/6 − (J + J′)┘ (whereK does not K = (min(200, K_(max, N)), K_(max, N)], where K_(max, N) =include a CRC bit) └5N/6 − (J + J′)┘ where a K value making a code rateless than 1/8 is not considered. Encoding length N {64, 128, 256, 512,1024} Decoding algorithm LLR min-sum based decoding algorithm for alist-X Size of a list X 1, 2, 4, 8, 16 (Only eight optimum paths areused for CRC checking) Construction CA polar method (J + J′) quantity 19bits (0b10100010101101111001, where the last bit is d19)

SNR values required for a BLER to reach 10⁻² and 10⁻³ are evaluated.That is, sequences A and B are given, and each combination (N, K) isexamined based on the simulation parameters in the foregoing table. Forexample, for N=64 and K=10, an SNR value required for a polar code,using the sequence A, to reach BLER=10⁻² is denoted as HA, and an SNRvalue required for a polar, using the sequence B, to reach BLER=10⁻² isdenoted as HB. Their difference HA−HB is compared with a giventhreshold. When the difference is greater than the threshold, it denotesthat the sequence B wins, and when 1 is added to a quantity of timesthat the sequence B wins, 1 is added to a quantity of times that thesequence A fails. When the difference is less than a negative threshold,it denotes that the sequence A wins, and when 1 is added to a quantityof times that the sequence A wins, 1 is added to a quantity of timesthat the sequence B fails. When the difference is less than or equal tothe threshold and is greater than or equal to the negative threshold, itdenotes that the two sequences have same performance, and neither ofquantities of times that the sequence A and the sequence B win isincreased. Further, SNR values required for the sequences A and B toreach BLER=10⁻³ are examined, their difference is compared with thethreshold, and an operation is further performed on a quantity of wins.

Steps for determining the threshold are as follows:

when a length K of to-be-encoded information is less than or equal to200, it denotes that PerfThresh_K=0.1 dB; and when K is greater than200, it denotes that PerfThresh_K=0.3 dB;

when a quantity L of decoding lists is equal to 1, PerfThresh_L=0.4 dB;when L=2, PerfThresh_L=0.2 dB; and when L is another value,PerfThresh_L=0.1 dB; and

a larger one of the foregoing two thresholds is used as a finalthreshold, that is, PerfThresh=max(PerfThresh_K, PerfThresh_L).

A specific sequence comparison procedure is as follows:

Step 1: Compute a quantity of wins, a quantity of failures, and anoverall quantity of failures of each sequence. A sequence A is taken,and is compared with the sequence B in each simulation instance. Foreach simulation instance: if performance of A is poorer than that of Bby PerfThresh, 1 is added to a quantity FailCount_AB of failures of A toB; if the performance of A is better than that of B by PerfThresh, 1 isadded to a quantity WinCountAB of wins of A to B; and if(FailCount_AB−WinCountAB)/Total quantity of simulation instances >2%, 1is added to an overall quantity OverallFail_A of failures of A. Thesequence A is compared with a sequence C in each simulation instance.For each simulation instance: if performance of A is poorer than that ofC by PerfThresh, 1 is added to a quantity FailCount_AC of failures of Ato C; if the performance of A is better than that of C by PerfThresh, 1is added to a quantity WinCount_AC of wins of A to C; if(FailCount_AC−WinCountAC)/Total quantity of simulation instances >2%, 1is added to an overall quantity OverallFail_A of failures of A. Forsequences D to N, repeat this process. The sequence B is taken, and iscompared with the sequence B in each simulation instance, and the restcan be deduced by analogy. The sequence N is taken, and is compared withthe sequence A in each simulation instance, and the rest can be deducedby analogy. A sequence with a smallest overall quantity OverallFail offailures is selected.

Step 2. If a plurality of sequences, namely, A to M, each have a minimumoverall quantity OverallFail of failures. A sequence A is compared witha sequence B in each simulation instance. For each simulation instance:if performance of A is better than that of B by PerfThresh, 1 is addedto a quantity WinCount_AB of wins of A to B. The sequence A is comparedwith a sequence C in each simulation instance. For each simulationinstance: if performance of A is better than that of C by PerfThresh, 1is added to a quantity WinCount_AC of wins of A to C, and a totalquantity of wins of A is WinCountA=ΣWinCount_AB . . . AM. This processis repeated until M is computed. For sequences of B to M, repeat thisprocess. A sequence whose total quantity WinCount of wins is largest isselected. It is assumed that the sequence is the sequence W.

Step 3: The sequence W having a largest quantity of wins is given. If asequence x exists, where a quantity of wins of x to W is greater than aquantity of wins of W to x, that is, WinCount_xW>WinCountWx, thesequence x is also selected for a next round.

Step 4: If a plurality of sequences are selected, a final sequence isdetermined through voting.

That the sorted sequence is a Q sequence is used as an example. A methodfor obtaining the sorted sequence applied in this embodiment of thisapplication roughly includes two steps:

First, sequences having optimum performance are sequentially obtainedaccording to the performance determining rule when the mother codelength is 64, 128, 256, 512, and 1024.

For convenience of description, the sequence obtained when the mothercode length is 64 is denoted as a first sequence or Q₆₄, the sequenceobtained when the mother code length is 128 is denoted as a secondsequence or Q₁₂₈, the sequence obtained when the mother code length is256 is denoted as a third sequence or Q₂₅₆, the sequence obtained whenthe mother code length is 512 is denoted as a fourth sequence or Q₅₁₂,and the sequence obtained when the mother code length is 1024 is denotedas a fifth sequence or Q₁₀₂₄.

Second, the five sequences are combined to obtain an updated sequencehaving a length of 1024, and the updated sequence is used as the sortedsequence applied in this embodiment of this application.

First, a first subsequence in which a sequence number is less than orequal to 64 in the second sequence is obtained, that is, a set ofelements whose values are less than or equal to 64 in Q₁₂₈. A set offirst (64−t₁+1) sequence numbers sorted top in the first subsequence isdetermined, and is denoted as P_(64-t) ₁ ₊₁. Sorting that is of thefirst (64−t₁+1) sequence numbers in the first subsequence and that is inthe first subsequence is updated based on sorting that is of the first(64−t₁+1) sequence numbers in the first subsequence and that is in thefirst sequence, and a to-be-compared second sequence is obtained basedon an updated first subsequence. That is, sorting of values of elementsin P_(64-t) ₁ ₊₁ is found in Q₆₄, and the sorting is used tosequentially replace sorting that is of the first (64−t₁+1) sequencenumbers in the first subsequence and that is in the first subsequence,to obtain Q₁₂₈*, where Q₁₂₈* may be referred to as the to-be-comparedsecond sequence. t₁ is a positive integer, and includes but is notlimited to a minimum information bit quantity plus a cyclic redundancycheck (CRC) bit quantity and a parity check (PC) bit quantity. Forexample, t₁ is the information bit quantity plus a CRC length accordingto the performance determining rule, and t₁=8+19=27, where 8 indicatesthe information bit quantity, and 19 indicates the CRC length. Sequencenumbers corresponding to k₁ most reliable locations are selected basedon a first target length k₁ separately from the second sequence and theto-be-compared second sequence, and encoded-codeword performance resultsare separately obtained based on the selected sequence numbers and agenerated second intermediate result sequence, where the secondintermediate result sequence includes (k₁−1) selected sequence numbers,the target length k₁ sequentially ranges from t₁ to k_(max) ^((M)), andk_(max) ^((M)) is a maximum information bit length when the mother codelength is M=64. A sequence number for which optimum performance isobtained is selected according to a performance determining rule, andthe second intermediate result sequence is updated based on the selectedsequence number for which the optimum performance is obtained. Anupdated second intermediate result sequence obtained when k₁ is set tok_(max) ^((M)) is used as the updated first subsequence, and the updatedfirst subsequence is placed in the second sequence, to obtain an updatedsecond sequence. The updated second sequence may also be denoted as Q₁₂₈^(opt). That is, from k₁=27 to k₁=64, each time a value of k₁ is taken,performance of polar codes separately constructed based on Q₁₂₈ andQ₁₂₈*, that is, performance of polar codes of (M=128, K₁), is compared,where M is the code length, K₁ is a length of an information bitsequence number set. It may be understood that, in this case,performance of a polar code of (M=128, K₁) is examined by considerationof performance of a polar code of (M=64, K₁). Each time a sequencenumber having better performance is selected, the sequence number is putinto Q₁₂₈ ^(opt). When polar codes constructed by using the twosequences Q₁₂₈ and Q₁₂₈* have same performance, the sequence number isdirectly put into Q₁₂₈ ^(opt).

Next, similarly, a second subsequence that is in the third sequence andin which a sequence number is less than or equal to 128 is obtained.Sorting that is of first (128−t₂+1) sequence numbers in the secondsubsequence and that is in the second subsequence is updated based onsorting that is of the first (128−t₂+1) sequence numbers in the secondsubsequence and that is in the updated second sequence. A to-be-comparedthird sequence is obtained based on an updated second subsequence.Sequence numbers corresponding to k₂ most reliable locations areselected based on a second target length k₂ separately from the thirdsequence and the to-be-compared third sequence. Encoded-codewordperformance results are separately obtained based on the selectedsequence numbers and a generated third intermediate result sequence,where the third intermediate result sequence includes (k₂−1) selectedsequence numbers, the second target length k₂ sequentially ranges fromt₂ to k_(max) ^((M)), and k_(max) ^((M)) is the maximum information bitlength when the mother code length is M=128. A sequence number for whichoptimum performance is obtained is selected according to the performancedetermining rule, and the third intermediate result sequence is updatedbased on the selected sequence number for which the optimum performanceis obtained. An updated third intermediate result sequence obtained whenk₂ is set to k_(max) ^((M)) is used as the updated second subsequence,and the updated second subsequence is placed in the third sequence, toobtain an updated third sequence. Popularly speaking, Q₁₂₈ ^(opt) andQ₂₅₆ are taken, and a set of first (128−t₂+1) elements whose sequencenumbers are less than or equal to 128 in Q₂₅₆ is denoted as P_(128-t) ₂₊₁. An order of elements included in P_(128-t) ₂ ₊₁ is found in Q₁₂₈^(opt), and based on the order, an order that is of first (128−t₂+1)sequence numbers in the second subsequence and that is in the secondsubsequence is replaced, to obtain a sequence Q₂₅₆* having a length of256. t₂ is a positive integer, and includes a minimum information bitquantity plus a CRC bit quantity and a PC bit quantity. For example, t₂is the information bit quantity plus a CRC length according to theperformance determining rule, and t₂=8+19=27. From k₂=t₂ to k₂=128, eachtime a value of k₂ is taken, performance of polar codes separatelyconstructed based on Q₂₅₆ and Q₂₅₆*, that is, performance of polar codesof (M=256, K₂), is compared, where M is the code length, K₂ is a lengthof an information bit sequence number set. It may be understood that, inthis case, performance of a polar code of (M=256, K₂) is examined byconsideration of performance of a polar code of (M=128, K₂). Each time asequence number having better performance is selected, the sequencenumber is put into Q₁₂₈ ^(opt). When polar codes constructed by usingthe two sequences Q₂₅₆ and Q₂₅₆* have same performance, the sequencenumber is directly put into Q₂₅₆ ^(opt).

Next, similarly, a third subsequence that is in the fourth sequence andin which a sequence number is less than or equal to 256 is obtained.Sorting that is of first (256−t₃+1) sequence numbers in the thirdsubsequence and that is in the third subsequence is updated based onsorting that is of the first (256−t₃+1) sequence numbers in the thirdsubsequence and that is in the updated third sequence, and ato-be-compared fourth sequence is obtained based on an updated thirdsubsequence. Sequence numbers corresponding to k₃ most reliablelocations are selected based on a third target length k₃ separately fromthe fourth sequence and the to-be-compared fourth sequence, andencoded-codeword performance results are separately obtained based onthe selected sequence numbers and a generated fourth intermediate resultsequence, where the fourth intermediate result sequence includes (k₃−1)selected sequence numbers, the third target length k₃ sequentiallyranges from t₃ to k_(max) ^((M)), and k_(max) ^((M)) is the maximuminformation bit length when the mother code length is M=256. A sequencenumber for which optimum performance is obtained is selected accordingto the performance determining rule, and the fourth intermediate resultsequence is updated based on the selected sequence number for which theoptimum performance is obtained. An updated fourth intermediate resultsequence obtained when k₃ is set to k_(max) ^((M)) is used as theupdated third subsequence, and the updated third subsequence is placedin the fourth sequence, to obtain an updated fourth sequence. Popularlyspeaking, Q₂₅₆ ^(opt) and Q₅₁₂ are taken, and a set of first (256−t₃+1)elements whose sequence numbers are less than or equal to 256 in Q₅₁₂ isdenoted as P_(256-t) ₃ ₊₁. An order of elements included in P_(256-t) ₃₊₁ is found in Q₂₅₆ ^(opt), and based on the order, an order that is offirst (256−t₃+1) sequence numbers in the third subsequence and that isin the third subsequence is replaced, to obtain a sequence Q₅₁₂* havinga length of 512. t₃ is a positive integer, and includes a minimuminformation bit quantity plus a CRC bit quantity and a PC bit quantity.For example, t₃ is the information bit quantity plus a CRC lengthaccording to the performance determining rule, and t₃=8+19=27. Fromk₃=t₃ to k₃=256, each time a value of k₃ is taken, performance of polarcodes separately constructed based on Q₅₁₂ and Q₅₁₂*, that is,performance of polar codes of (M=512, K₃), is compared, where M is thecode length, K₃ is a length of an information bit sequence number set.It may be understood that, in this case, performance of a polar code of(M=512, K₃) is examined by consideration of performance of a polar codeof (M=256, K₃). Each time a sequence number having better performance isselected, the sequence number is put into Q₅₁₂ ^(opt). When polar codesconstructed by using the two sequences Q₅₁₂ and Q₅₁₂* have sameperformance, the sequence number is directly put into Q₅₁₂ ^(opt).

Finally, similarly, a fourth subsequence that is in the fifth sequenceand in which a sequence number is less than or equal to 512 is obtained.Sorting that is of first (512−t₄+1) sequence numbers in the fourthsubsequence and that is in the fourth subsequence is updated based onsorting that is of the first (512−t₄+1) sequence numbers in the fourthsubsequence and that is in the updated fourth sequence, and ato-be-compared fifth sequence is obtained based on an updated fourthsubsequence. Sequence numbers corresponding to k₄ most reliablelocations are selected based on a fourth target length k₄ separatelyfrom the fifth sequence and the to-be-compared fifth sequence, andencoded-codeword performance results are separately obtained based onthe selected sequence numbers and a generated fifth intermediate resultsequence, where the fifth intermediate result sequence includes (k₄−1)selected sequence numbers, the fourth target length k₄ sequentiallyranges from k₄ to k_(max) ^((M)), and k_(max) ^((M)) is the maximuminformation bit length when the mother code length is M=512. A sequencenumber for which optimum performance is obtained is selected accordingto the performance determining rule, and the fifth intermediate resultsequence is updated based on the selected sequence number for which theoptimum performance is obtained. An updated fifth intermediate resultsequence obtained when k₄ is set to k_(max) ^((M)) is used as theupdated fourth subsequence, and the updated fourth subsequence is placedin the fifth sequence, to obtain an updated fifth sequence. Popularlyspeaking, Q₅₁₂ ^(opt) and Q₁₀₂₄ are taken, and a set of first (512−t₄+1)elements whose sequence numbers are less than or equal to 512 in Q₁₀₂₄is denoted as P_(512-t) ₄ ₊₁. An order of elements included in P_(512-t)₄ ₊₁ is found in Q₅₁₂ ^(opt), and based on the order, an order that isof first 512−t₄+1) sequence numbers in the fourth subsequence and thatis in the fourth subsequence is replaced, to obtain a sequence Q₁₀₂₄*having a length of 1024. t₄ is a positive integer, and includes aminimum information bit quantity plus a CRC bit quantity and a PC bitquantity. For example, t₄ is the information bit quantity plus a CRClength according to the performance determining rule, and t₄=8+19=27.From k₄=t₄ to k₄=512, each time a value of k₄ is taken, performance ofpolar codes separately constructed based on Q₁₀₂₄ and Q₁₀₂₄*, that is,performance of polar codes of (M=1024, K₄), is compared, where M is thecode length, K₄ is a length of an information bit sequence number set.It may be understood that, in this case, performance of a polar code of(M=1024, K₄) is examined by consideration of performance of a polar codeof (M=1024, K₄). Each time a sequence number having better performanceis selected, the sequence number is put into Q₁₀₂₄ ^(opt). When polarcodes constructed by using the two sequences Q₁₀₂₄ and Q₁₀₂₄* have sameperformance, the sequence number is directly put into Q₁₀₂₄ ^(opt).

The updated fifth sequence is the sorted sequence used to encode theto-be-encoded bits in this embodiment of this application. The sortedsequence corresponds to the maximum mother code length of 1024.Optionally, because the sorted sequence obtained by using the foregoingmethod satisfy a nesting characteristic, when the sorted sequence havingthe maximum mother code length is determined, another sorted sequencehaving a shorter mother code length may be obtained based on the sortedsequence. For example, sorted sequences having mother code lengths of64, 128, 256, and 512 are obtained.

The following specifically describes how to obtain the first sequence tothe fifth sequence in the foregoing steps.

Specifically, one sequence number is sequentially selected from (M−k₅+1)sequence numbers based on a fifth target length k₅, and each time onesequence number is selected, an encoded-codeword performance result isobtained based on the selected sequence number and a generatedintermediate result sequence. The intermediate result sequence includes(k₅−1) selected sequence numbers, the (M−k₅+1) sequence numbers arenon-overlapping with the intermediate result sequence, the target lengthk₅ sequentially ranges from 1 to k_(max) ^((M)), where k_(max) ^((M)) isthe maximum information bit length when the mother code length is M, andk_(max) is a length of a maximum information bit vector supported by asystem, for example, k_(max) is a value described in the performancedetermining rule, that is, 5N/6−(J+J′). Herein, N may be actuallyconsidered as M, that is, different code lengths correspond to differentvalues of k_(max). A sequence number for which optimum performance isobtained is selected according to the performance determining rule, andthe intermediate result sequence is updated based on the selectedsequence number for which the optimum performance is obtained. M is aninteger power of 2, M is the mother code length, and the mother codelength is 64, 128, 256, 512, or 1024.

For example, when M=64, an initial value of the intermediate resultsequence Q_(N) is set to an empty set, an initial value of k₅ is set to0, and k₅=k₅+1 is performed to select a sequence number i_(k5) of apolar channel, where i_(k5)∈[1, N] and i_(k5)∉Q_(N). To be specific, apolar channel is selected from undetermined polar channels, and selectedi_(k5) is placed at the first bit in the sequence Q_(N), so that updatedQ_(N) is an optimum sequence obtained according to the performancedetermining rule for performance of a polar code of (M=64, K=k₅).Whether k₅ is greater than or equal to k_(max) is determined. If k₅ isnot greater than or equal to k_(max), return to perform k₅=k₅+1. If k₅is greater than or equal to k_(max), the operation is ended.

For another example, when M=128, an initial value of the intermediateresult sequence Q_(N) is set to an empty set, an initial value of k₅ isset to 0, and k₅=k₅+1 is performed to select a sequence number i_(k5) ofa polar channel, where i_(k5)∈[1, N] and i_(k5)∉Q_(N). To be specific, apolar channel is selected from undetermined polar channels, and selectedi_(k5) is placed at the first bit in the sequence Q_(N), so that updatedQ_(N) is an optimum sequence obtained according to the performancedetermining rule for performance of a polar code of (M=128, K=k₅).Whether k₅ is greater than or equal to k_(max) is determined. If k₅ isnot greater than or equal to k_(max), return to perform k₅=k₅+1. If k₅is greater than or equal to k_(max), the operation is ended.

In this way, sequences having mother code lengths of 64, 128, 256, 512,and 1024 separately may be obtained. That is, the first sequence to thefifth sequence may be obtained.

As described above, after the Q sequence is obtained, in this embodimentof this application, a Z sequence may be obtained based on the Qsequence.

This embodiment of this application provides some optional examples ofthe sorted sequence as follows. Using the following sorted sequences canhelp improve encoding/decoding performance of a polar code. Thefollowing sequences may be obtained by using the method provided in thisembodiment of this application, or may be obtained by using anotherpossible method.

It should be noted that the foregoing sorted sequences are merelyexamples, and application of the sequences to a polar encoding processhelps improve encoding/decoding performance of a polar code. For anyexemplified sorted sequence, on a premise of not affecting an overalleffect of the sequence, adjustments or equivalent replacements in thefollowing several aspects may be included but are not limited:

1. Locations of fewer elements in the sorted sequence are exchanged. Forexample, a sequence number location may be adjusted by a specifiedmagnitude, for example, the specified magnitude is 5. A location of anelement whose sequence number is 10 may be adjusted by left and rightfive locations.

2. Some elements in the sorted sequence are adjusted, but channel setsthat are used to transmit T-bit information and that are selected basedon the sorted sequence are consistent or similar.

3. The sorted sequence includes N elements from 1 to N, and the Nelements from 1 to N represent sequence numbers of N polar channels.Actually, the sequence numbers of the N polar channels may alternativelystart from 0 and end up with N−1, that is, subtracting 1 from thesequence numbers in the foregoing sorted sequence. This is also asequence number form in the foregoing computation manner. Certainly, asequence number or an identifier of the polar channel may alternativelybe represented in another manner. The specific representation mannerdoes not affect a specific location of the polar channel in the sortedsequence.

4. Sequence numbers of N polar channels in the sorted sequence arearranged in descending order of reliability of the N polar channels.Actually, sequence numbers of N polar channels may alternatively bearranged in ascending order of reliability of the N polar channels. Thatis, elements in the foregoing sorted sequence are arranged in reverseorder or in inverse order.

5. The foregoing sorted sequence may alternatively be represented byusing normalized reliability sequences or equivalent reliabilitysorted-sequences of various channels. For example, a sorting location ofa channel x in the foregoing sequence is n (where a smallest sequencenumber in the sorted sequence is denoted as 1). In this case,reliability of the channel may be represented as n or normalized n/N,where N is a length of the sorted sequence.
